RAILWAY-SWITCH.

Specification of Letters Patent.

Patented May *7, 1912.

Application filed. February 9, 1911, Serial No. 607,501. Renewed March22, 1912. Serial No. 685,416.

To all whom it may concern:

Be it known that I, FRANK CHAMNEss, a citizen of the United States,residing at Huntington, in the county of Huntington, State of Indiana,have invented certain new and useful Improvements in Railway- Switches;and I do hereby declare the fol- ].owing to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to railway switches.

The object of the invention resides in the provision of an improvedconstruction of railway switch which will increase the efficiency andsafety of devices of this char acter.

With these and other objects in view, the invention consists in thedetails of construct-ion and arrangement and combination of parts to behereinafter more fully described and particularly pointed out in theappended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views; and in-which,

Figure 1 is a plan view of a railway switch constructed in accordancewith the invention; Fig. 2, a detail perspective view of the slidingswitch point employed in the switch; and Fig. 3, a detail perspectiveview showing part of the connections between the pivoted frog and thesliding switch point.

Referring to the drawings, A indicates the main track and B a siding,the entrance to the latter from the main track being controlled by aswitch to be hereinafter described. The main track A includes rails 10and 11, while the siding B includes rails 12 and 13.

The switch construction proper comprises a pair of switch rails 14 and15 directed respectively toward the siding and the main track, theswitch rail 14 being positioned to con stitute a continuation of therail 13 of the siding, while the switch rail 15 is positioned toconstitute a continuation of the rail 11 of the main track. The adjacentends of the rails 11 and 13 of the main track and siding and the switchrails 14 and 15 are connected together by means of a plate 16 whichrests upon and is secured to ties G. Pivotally mounted upon the plate 16is a frog 17 which is positioned so that its free end may be movedselectively into engagen'lent with the switch rails 14 and 15. When thefrog 17 is in engagement with the switch rail 14, it will be apparentthat said switch rail, frog and rail 13 will form a continuous rail lineand serve to properly direct a train which has been previously switched,in a manner to be hereinafter described, into the siding B. It willlikewise be apparent that when the free end of the frog 17 is disposedin engagement with the switch 15, said switch rail, frog and rail 11will constitute a continuous rail line. The frog 17 is provided with alaterally projecting ear 18 to which is connected one end of a link 19.The other end of this link 19 is operatively connected to an actuatingmechanism D disposed atone side of the track 12. This actuatingmechanism is so constructed that same may be actuated to effect theselective movement of the frog 17 into engagement with either the switchrail 14 or switch rail 15. The free end of the frog 17 has its lowerside cut away as at 20 and depending from the upper wall of this cutaway portion 20 is a stud 21. Pivotally mounted upon the plate 16adjacent the free end of the frog 17 is an angle lever comprising arms22 and 23, the latter of which is connected at its free end to the stud21 so that the movement of the frog 17 on its pivot will also effect amovement of said angle lever. The arm 22 of the angle lever extendsthrough a slot 24 in the web of the end of the switch rail 14 adjacentthe frog 17. This switch rail 14 is also provided in the web of itsopposite end with a slot 25, said last named end of the switch rail 14being scarfed as at 26 to form an inclined end face directed toward therail 10 of the main track, the recess 25 extending through this scarfedportion of said switch rail.

Projecting from the inclined face 26 of the switch rail. 14 on oppositesides of the recess 25 respectively are pins 27 and 28 which extendthrough openings 29 and 30 respectively in a switch point 31. Thisswitch point 31 is provided with a laterally extending car 32 disposedbetween the openings 29 and 30 and projecting through the recess 25 inthe switch rail. 14. The pins 27 and 28 are provided with enlarged headsat their outer ends so as to secure the switch point 31 fromdisengagement with the switch rail 14. From this construction, it willbe apparent that the switch point 31 is capable of a sliding movementlongitudinally of the switch rail 14: and'this movement of said switchpoint in one direction will position the latter so as to open theswitch, while the movement thereof in the opposite direction will serveto close the switch. In order to effect the sliding movement of theswitch point 21 simultaneously with the pivotal movement of the frog 17the ear 32 is connected to the arm 22 of the angle lever by means of alink 33 so that when the pivoted frog is moved into engagement with theswitch rail 14:, the switch point 81 will he slid longitudinally of saidswitch rail to a position for closing the switch, while the oppositemovement of said frog will shift the switch point to a position thatwill effect the opening of the switch.

What is claimed is In a railway switch, a main track, a siding, switchrails directed respectively to one of the rails of the siding and one ofthe rails of the main track, a frog pivotally mounted between the endsof the switch rail and ends of the siding and main track to which saidswitch rails are directed and adapted to be moved into engagementselectively at its free end with said switch rails to form continuousrail lines, means for moving said frog on its pivot, a switch pointslidably mounted on the switch rail directed to the siding for movementlongitudinally of said switch rail and controlling entrance to thesiding from the main track, connect-ions between said switch point andfrog whereby the movement of the free end of the latter into engagementwith the switch rail directed to the siding will move said switch pointto open the switch and the movement of the free end of said frog intoengagement with the switch rail directed to the main track will movesaid switch point. to close the switch.

In testimony whereof, I afiix my signature, in presence of twowitnesses.
